约旦南部佩特拉地区恶劣的山区环境被古代工程师改造，以供应纳巴泰/罗马城市佩特拉的食物和水。该地区是通过安装扩大的径流梯田系统和水工结构来开垦的。到目前为止，农业梯田系统的年代是以表面陶器为基础的，系统的年代还在争论中。在这项研究中，光激发发光(OSL)和放射性碳测年技术被成功地应用于这些阶地系统的年代测定。样本取自农业梯田的填充物和墙下，以确定农业梯田的建设、使用和废弃的时间顺序。结果表明，佩特拉地区的径流耕作大约在公元时代开始，建设、使用和维护至少持续到公元800年。
The unfavourable mountainous environment of the Petra region in southern Jordan was modified by ancient engineers to supply the Nabataean/Roman city of Petra with food and water. The area was reclaimed by installing extended runoff terrace systems and hydraulic structures. The agricultural terrace systems have so far been dated based on surface pottery, and the chronology of the systems is under debate. In this study, optically stimulated luminescence (OSL) and radiocarbon dating techniques were successfully applied to date these terrace systems. Samples were taken from the fills of agricultural terraces and underneath their walls to determine the chronology of the construction, use and abandonment of the agricultural terraces. The results suggest that runoff farming in the Petra region started around the beginning of the Common Era, and construction, use and maintenance lasted at least until 800 AD.
